nova 注入adminpass 添加用戶等設置

compute node install

yum install libguestfs python-libguestfs libguestfs-tools-c

compute node config

[libvirt]

inject_password=true

inject_key=true

inject_partition=-1

restart nova compute

systemctl restart openstack-nova-compute

設置root/adminstrator的密碼

nova boot --admin-pass 

添加新用戶

nova boot --user-data

 user-data example

#!/bin/sh
passwd ubuntu<<EOF
ubuntu
ubuntu
EOF
sed -i 's/PasswordAuthentication no/PasswordAuthentication yes/g' /etc/ssh/sshd_config
service ssh restart

 備注：

1 https://cloud-images.ubuntu.com/ 上的ubuntu vm用該方法設置password

2 如果需要nova set-password起作用，需要image中裝有qga，另外制作image時，需要設置meta中的 hw_qemu_guest_agent為yes

鏡像中還需要指定用戶名。可以參考m版的nova代碼

def set_admin_password(self, instance, new_pass):
        self._can_set_admin_password(instance.image_meta)

        guest = self._host.get_guest(instance)
        user = instance.image_meta.properties.get("os_admin_user")
        if not user:
            if instance.os_type == "windows":
                user = "Administrator"
            else:
                user = "root"
        try:
            guest.set_user_password(user, new_pass)

追加windows 密碼設置的舊方法(不需要qga，需要cloudbase-init)

nova boot --key-name --meta admin-pass=yourpassword

事先在windows鏡像中配置好cloudbase-init 來指定用戶名。比如sds的環境中使用的鏡像設置的用戶名是admin
